Lithium slag concrete expanding agent
The invention discloses a lithium slag concrete expanding agent. The expanding agent is prepared from the following materials; the invention relates to a high-aluminum-content cement mortar which is prepared from the following raw materials in parts by weight: 5-7 parts of lithium slag, 2-3 parts of anhydrite, 1-2 parts of high-aluminum clinker, 1-3 parts of polyethyl alcohol ether, 0-1 part of sugar calcium, 1-3 parts of light water glass, 2-6 parts of calcined gypsum, 2.5-7.5 parts of calcined lime, 4.5-13.5 parts of anhydrous sodium sulphate and 1-4 parts of a modifier. Compared with the prior art, the invention has the advantages of wide raw material source, low cost, no reduction of the later strength of the cement, and no change of the cement production process.
本发明公开了一种锂渣类混凝土膨胀剂，所述膨胀剂由以下材料制备；5‑7份锂渣、2‑3份硬石膏、1‑2份高铝熟料、1‑3份聚乙醇醚、0‑1份糖钙、1‑3份轻质水玻璃、2‑6份烧石膏、2.5‑7.5份烧石灰、4.5‑13.5份元明粉以及1‑4份改性剂。本发明与现有的技术相比的优点在于：本发明原料来源广泛，成本低、不降低水泥后期强度，不改变水泥生产工艺。
